MiCasa Legal provides assistance with business establishment in Japan.
The three most common types of businesses established by overseas companies in Japan are Kabushiki-Kaisha(K.K.), Godo-Kaisha(G.K.) and branch office.
Descriptions of each type of establishment are as follows.
Please feel free to contact us for more details.

Kabushiki-Kaisha (K.K.) and Godo-Kaisha (G.K.)

K.K. and G.K. are subsidiary companies of your parent company and are considered separate legal entities under Japanese law. Liability is limited to your investment in the subsidiary itself and does not extend to your parent company.
The main differences between these types of companies are in regards to their different structures of corporate governance. Generally speaking, K.K. is similarly structured to US corporation (Inc.), while G.K. is similarly structured to US limited liability company (LLC).
K.K. is the most commonly established and traditional type of company in Japan and is subject to many rules under the Companies Act.
G.K. is a newer type of company and has been gaining more popular lately, since the structure and method of the operations are simpler than K.K.. For example, G.K. does not need to hold an annual ordinary meeting of members(owners) and members have no term of office to renew.
For small companies, G.K.s can be a more flexible option with less ongoing compliance. However, K.K.s are more trusted by customers in Japan since the company type is much more widely recognized.

Branch Office

A branch office is an extension of an existing overseas business in Japan and is not considered a separate legal entity. As such, your company would have unlimited liability for any claims against its Japanese branch office.
This type is usually only recommended for small businesses in Japan.
